`The invention relates to` portable' moldingr nm' ninfas. l

The object of the invention is to provide nu improved portable structure with a mold*- inf; machine mounted thereon and which niny be propelled over the floor of a moldY hilf room." In the operation of mil/chilies it the type exemplified n-our Patents Nos.

'.:mfll -.md 1,309,836. it has been found desirable to improve the construction sothat I they would withstand the" Severe weer and wieg-fe to which they ere subjected in` foundry practice, and one of the objects 'of the invention vis to provide aV structure whirh will zitta-in this 'reslt .Another object of the invention is to provide, ir'nproved niechnnisnr for propelling the portnhle carriage over the foundry floor. Other objects of the invention will appear from the detailed4 description thereof.

Yhe invention consists in `the several novell features hereinafter set forth and more par tieulurly defined by elamsiat the conclu# sion hereof.

ln the drawings: AFi f., 1 is n side elevation oF n nun-hine embofying the invention. Fig. 2 is a horizontal section on line 2 2 of Fig. l.. truck viewed from thegopposite side to that shown in Fig. 1. Fig. 4 is a vertical se@ lion. Fig. 5 is a transverse section taken on line .5-5 of Fig. 2. Fig. 6 is n. section tnlren on line Vof Fig'. 2. Fig 7 is u secfion taken on line 7 7 of Fig. 2.

The vinvention is exemplified in a. structure froniprising a truck-frame which is mounted upon wheels adapted to travel on merits in the molding room floor. This frame comprises sides l() and l1 which are rigidly cross connected to form :t rigid structure by pipes or tubes l2 and 13. Pipe ,of the truck is' supported .by plain f ueed rwheels 27 which are mounted on stud-shafts formed on thtrack A ruck 23. Grooves 3-1 d Fig. 3 is a'visirde elevation of the` 'grooves in advance of the wheels V22. By

Pipe 12 kis clamped in seats 17 formed in lugs onthe frame-sides byI U-bolts 18 and a elamping bracket 19 and bolts' 20. ln prne- ,tiee,. these `machines are of onsiderable width and it hesbeen found thiit a frame mede `upof sides and pipes, as" sete forth, 'is well` adapted to withstand the severe stresses to whiehthe structure is subjected in `prnetice. The rear of the truelels carried bv ii pair of trnction7wheel's 21 having' toothed perxpheries 22 to engage' wrrespondingly toothed racks 23 formed on the tracks` 24 whichere set into the floor of themoldng room.4 These wheels are eonjointl'y ydriven to propel the truck, by mechanism hereinafter 'set forth.' The hub of each tractionwheel 21 fits over and bears, as at 25, upon one end` ofthe tube 13 and e. ,shaft26 ex# tends through thetube 13 and is keyed at its endstoV the hubs of the traction-wheels 2l sothatthey will be' seeured together for .conjoint rota-filon toestuse both sides ,of the machine toadvzmce equally, wvhielris desirable to avoid twisting 'streinson the truck and the parts mounted'theren. The jfmnt '28Y secured in housingsvtl formed on .the

frame-sidesvl() afndll respectively. Wheels 27 are disposed inwardly of the toothed trection wheels 21 and rollen a Hat Vtt'etld 3() inwiirll of the 32fa`re ormed at the sides of the teeth-o rwclt 23` so that the Sand which finds its way into the'spaees between the teeth of thereck und the wheels 21mm fscapef'lternlly. Cleaners 33 and 3i which are fixed to thefradiesides, exten into the grooves 31 and `32 and clealn' them out in the rer of the traction-wheels, as the truck travels'over the Hoor. An addi tional cleaner 33* -is hinged to either side of the frame ,und is pressed by ai spring 33 to ride over :und between the teeth and in the grooves 31 and 32 to lclean the racksand supporting` the tube 13 in the frame-sides and extendin its ends vinto the hubs of the traction-whee s 21 and extending the crosssheft 2G through the tube, the tube is made to serve not only as an-e'ective frame-member, but also as an enclosure for the` cross shaft which ositively drives one traction wheel from t e other, soboth sides of the truck will 4travel equidistantly.

A base for supporting the molding machine on the truck comprises a member 35 which is 4provided with a seat 36 bearing on pipe 13 and clamped thereto by 'bolts 37A and a member 38 which is bolted at 39 to member 35 vand is provided with a seat 4() to receive and engage the pipe l2 and is clamped thereto by U-bolts 4l. A standard 60 for' supporting the upper end of an elevator, hereinafter described, is also clamped on top of base-member 38 by U-bolts 4l. A post 42 is' rovided on the base-member 35. The mol ing machine mounted on the truck comprises an arm 44 pivoted on the post 42, a jib 45 pivoted to the'outer' end of-the arm 44, a sand-.projector 46 at the outer end of the jib, a motor 47 mounted on the jib and connected to drive the rotor of fthe sandzprojector 46,' a vibratory chute conveyor and riddle 48 mounted to swing with thea m 4,4, mecha-nism`49 for vibratinv thecli te tb deliver sand-onto a feedbelt 50 wlfich is mounted `to swing with ,the arm 45 and is adapted to Vdeliver sand to the projector '46. The latter may` be of the construction set forth in Letters Patent No. 1,309,833gso that a more detailed description is not deemed necessary. The construction of` the arm, jib,` mechanism Vfor operating the chute 48 and mechanism for driving the belt 50` may be of the 'same construction described andillustrated in our application for Letters Patent filed March 14, 1921, Serial No.452,068, to-which reference may be lhad for a more detailed illustration and description. Thismolding machine exemplifies one which-is mounted upon a truck and is adapted to bev operated to fill flasks beneath the ro'ector.

To kee.`sand supplie 'tothe molding mahineleih a pile on the floor ahead ofthe truck; a cross-conveyor, comprising hollowshaft 58 and' spiral blades.54l and 55 which are provided with blades 53 adapted to disintegratethe sand in the pile, 1s provided :the sand inwardly towards the to eonvefy center o he truck. Flange'd plugs 63 are `secured inl the ends of the hollovvy shaft 58.
